Flu-related deaths spike to 77 in Iowa

Flu-related deaths nearly doubled in a week's time according to new data from the Iowa Department of Public Health.

This week, 34 more flu-related deaths were reported, raising the total to 77 since October 1. So far, health officials say no children have died in Iowa because of the flu.

The predominant flu strain this season is AH3N2, which typically causes serious illnesses, hospitalizations and even death, particularly for those who are very young or old and those with weakened immune systems.

Health officials say it is not too late to get a flu shot, as the flu season will continue for months.
